NC as could be outing from other threads under my usual name.
Yesterday, me and DP celebrated being together for 10 years. We are engaged but have not been able to afford the wedding we want yet.
So, we were out, both had been drinking. DP said to me 'I am so glad I choose you!?'
This was a little confusing to me as when I met him he told me that he was single and had been single for over 8 months.
I questioned him and he told me that when he met me he had been 'seeing' someone for 5 months but it wasn't serious and once me and him became exclusive and were officially a couple he 'fucked her off'
I am really upset by this, he lied to me at the time and I also feel for this woman who was 'fucked off' because he met me. Also, we didn't become 'exclusive' for 6 weeks after meeting... so I asked him if he was still seeing her and with her during this time. He told me I was being silly and wouldn't answer the question. He is shocked by my reaction from something that happened a decade ago.
AIBU?
